Peony Yellow
Good Bad Bug bug? Why are dying my poppies?

I live in Paris, Ontario. My garden is a combination of raised beds of tomatoes, gladioli, hollyhocks, Shasta daisies, peonies, foxglove, bee balm, lilies, onions, chives, strawberries, Cotoneaster, bush blueberry, Jacob's Ladder, Sedum, and marigolds .. Today I saw a praying mantis in my garden. I also found a black fuzzy caterpillar with a strip bronze (now deceased), leaf insects jump shot baby, and a hair thin green-bug worms at the base of my roses (south facing front garden) … oh yes, and a black frog / toad. Q1. That one (s) in the garden-friendly bugs / amphibians – in other words, what should I be killing in sight? Q2. Why Icelandic poppies my dying and now my oriental poppies are following suit? They are in a garden bed facing south – a compost heap in full sun all day. The lower leaves turn yellow and then brown then die. The flowers are not affected until the plant is completely dead. They are planted Heuchera, iris, nepetas and thoughts.

I leave them alone. The praying mantis and the toad are trying to keep your garden free of errors.
